The omnivorous ground beetle, Pterostichus melanarius Illager (Coleoptera: Carabidae), is a ubiquitous inhabitant of western Oregon crop land. Because it is often the most abundant ground beetle, and attains densities that could lead to serious impacts on its prey sources, I sought to understand the overall diet composition, and specifically...
Foundation species are important components of ecosystems because they provide habitat and ameliorate stressful conditions for residents. This thesis considers the role of surfgrasses (Phyllospadix spp.) as dynamic foundation species on the coast of Oregon in two studies. Chapter 2, which presents an observational survey of two Phyllospadix congeners, investigates...
Arctic cod (Boreogadus saida) is an ecologically significant species that plays a critical role channeling energy throughout the Arctic marine food web. Arctic cod is uniquely adapted to occupy ice edge habitats, however, a basic understanding of its larval physiology and habitat requirements is lacking due to widespread sea ice...
Working waterfronts across the nation are under pressure. Land use priorities of local governments are changing in response to population growth, new economic pressures, and shifting policy and politics. In Oregon, the decline of fisheries and timber in economic importance followed by the growth of tourism and retirement services has...
The purpose of this research was to study teenagers'
consumer credit attitudes, knowledge, and use. More specifically,
the objectives were (1) to determine the relationships
between the variables attitudes, knowledge, and use, and

This research explores differences in environmental worldviews and connections to the land globally and more specifically in a case study of NGOs working in the Ecuadorian Cloud Forest. The aims of this project are to investigate different environmental worldviews expressed between western NGOs and non western local NGOs and to...
An assay is described to measure sterol uptake in
Saccharomyces cerevisiae. This assay involves specific
binding of radioactively labelled sterol to actively
growing yeast cells.
It was found that uptake does not occur in stationary
cultures and that some growth is necessary for FY3 , a
sterol auxotroph, to take...
